Product details
Overview
VESD26C1-02V-G3-08 from Vishay Semiconductors is a unidirectional ESD protection diode in SOD-523 package, designed for single-line signal line protection with 26 V reverse standoff voltage, 43–48 V clamping at 2.1 A pulse, and 14–21 pF capacitance at 1 MHz. It delivers ±20 kV IEC 61000-4-2 contact/air discharge immunity for USB, HDMI, and industrial sensor interfaces.
For engineers reviewing the VESD26C1-02V-G3-08 datasheet, VESD26C1-02V-G3-08 pinout, VESD26C1-02V-G3-08 application, or VESD26C1-02V-G3-08 equivalent, key selection criteria include clamping voltage under 2.1 A IEC 61000-4-5 surge, low 17.5 pF typical capacitance for high-speed data lines, thermal robustness to +150 °C junction, and SOD-523 footprint compatibility with space-constrained PCB layouts.
Technical Context
The VESD26C1-02V-G3-08 implements a single-channel unidirectional TVS structure optimized for low-capacitance transient suppression on DC-coupled signal paths. Its 26 V VRWM and 29.1 V typical breakdown (at 1 mA) define a precise overvoltage threshold before clamping activation.
Under IEC 61000-4-5 8/20 μs surge, it limits peak voltage to ≤48 V at 2.1 A while dissipating up to 100 W peak power. Dynamic resistance of 1.9 Ω (TLP, 100 ns) ensures fast response and minimal voltage overshoot during sub-nanosecond ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 26 V - maximum continuous operating voltage before leakage exceeds 0.1 μA; sets safe margin below system rail |
| Clamping Voltage | 43–48 V at 2.1 A, 8/20 μs - peak voltage seen by protected IC during worst-case surge; must stay below IC's absolute max rating |
| Capacitance | 14–21 pF at 0 V, 1 MHz - low enough to avoid signal integrity degradation on USB 2.0 or CAN FD lines |
| ESD Immunity | ±20 kV contact / ±20 kV air per IEC 61000-4-2 - meets automotive and industrial ESD stress requirements for exposed ports |
| Operating Temperature | −55 °C to +150 °C - supports under-hood automotive, industrial control, and outdoor IoT deployments |
| Package | SOD-523 - 1.3 × 0.85 × 0.7 mm footprint; compatible with standard 0201 reflow profiles and AOI inspection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ26A-E3/57T | DO-214AC package; 26 V VBR min; 400 W peak power; 200 pF capacitance | Higher clamping (~53 V), much larger footprint, unsuitable for high-speed data | Select only for high-energy, low-frequency power/signal lines where size and capacitance are secondary |
| TPD2E001DRYR | 2-channel bidirectional array; 0.9 pF typical capacitance; 5 V VRWM; SOT-553 | Lower voltage rating; dual-line protection; optimized for USB Type-C CC lines | Choose when protecting two low-voltage, ultra-high-speed lines (e.g., USB PD CC1/CC2) with strict <1 pF budget |
Compared with SMAJ26A-E3/57T, VESD26C1-02V-G3-08 offers 10× lower capacitance and 60% smaller footprint for data-line use; versus TPD2E001DRYR, it provides 5× higher VRWM for 24 V industrial I/O but lacks bidirectionality and dual-channel integration.

FAQ
What is the maximum clamping voltage of the VESD26C1-02V-G3-08 under IEC 61000-4-5 surge conditions?
The VESD26C1-02V-G3-08 clamps to a maximum of 48 V at 2.1 A peak pulse current (8/20 μs waveform), as specified in its Absolute Maximum Ratings table. This value ensures downstream ICs with ≤50 V absolute maximum ratings remain protected during standardized surge events. The VESD26C1-02V-G3-08 achieves this with a dynamic resistance of 1.9 Ω, limiting voltage overshoot during fast transients.
Is the VESD26C1-02V-G3-08 suitable for protecting USB 2.0 high-speed data lines?
Yes, the VESD26C1-02V-G3-08 is suitable for USB 2.0 data line protection due to its 14–21 pF capacitance (typical 17.5 pF at 1 MHz), which introduces negligible signal distortion at 480 Mbps. Its 26 V VRWM accommodates common 3.3 V or 5 V logic swings with safety margin, and its 48 V clamping stays below typical USB transceiver absolute maximum ratings. The SOD-523 footprint also fits tight routing constraints near connectors.
Does the VESD26C1-02V-G3-08 meet AEC-Q101 qualification?
The base VESD26C1-02V-G3-08 is not AEC-Q101 qualified; however, Vishay offers the VESD26C1-02V-HG3-08 variant with AEC-Q101 qualification for automotive applications. This variant shares identical electrical parameters and SOD-523 packaging but undergoes additional stress testing per AEC-Q101 Rev D. Always verify the suffix 'H' in the ordering code when automotive qualification is required.
What is the reverse leakage current of the VESD26C1-02V-G3-08 at its rated standoff voltage?
At 26 V reverse voltage (VR = 26 V), the VESD26C1-02V-G3-08 exhibits a maximum reverse leakage current (IR) of 0.1 μA, with typical values < 0.01 μA. This ultralow leakage ensures minimal power drain on battery-operated systems and avoids false triggering in high-impedance sensing circuits. The specification is verified at 25 °C and aligns with the device's 0.1 μA IR test condition stated in its Electrical Characteristics table.
How does the capacitance of the VESD26C1-02V-G3-08 vary with applied reverse voltage?
The VESD26C1-02V-G3-08 capacitance decreases with increasing reverse bias: it measures 14–21 pF at 0 V, dropping to ~10 pF at 10 V and ~7 pF at 20 V (per Fig. 4 in the datasheet). This voltage-dependent behavior is inherent to its PN-junction structure and must be considered in AC-coupled or dynamically biased signal paths. For DC-biased USB or RS-485 lines, the 0 V capacitance value governs high-frequency impedance.
